Abstract: This application provides a secondary battery, a battery module, and a device using a secondary battery as a power supply. The secondary battery includes an electrode assembly, a cap assembly, and current collection members. The electrode assembly includes a main body and tabs that extend from the main body. The cap assembly includes a cap plate, electrode terminals, and an insulation baffle. The electrode terminals are disposed on the cap plate. The insulation baffle is connected to a side of the cap plate, where the side is close to the main body. The current collection members are at least partly located between the insulation baffle and the main body, and each of the current collection members includes a tab connection portion connected to one of the tabs. The insulation baffle contains a first recess.
